Pumps

【Improvement】：
Slurry pump impeller and the casing are lined with Xinhai high wear-resistant rubber ensuring that the pump body is not subject to wear. In the same project, the service life of Xinhai slurry pump is 2 times longer than other metal pump life reaching the international top quality. The rubber liners wear index has reached 128%.

【Improvement】：
Xinhai rubber check valve is made of Xinhai 35 wear – resistant rubber with strong wear and corrosive resistance. Experiment shows that it be immersed in a concentration of 30% sulfuric acid or alkaline solutions; 48 hours later, the performance of the rubber has no obvious change, so the applicable range is very wide.
